Air cushion

ABSTRACT

An air cushion has a body and a supporting cushion. The supporting cushion is mounted inside of the body and has multiple hexagon-shaped holes. The holes are formed through the supporting cushion and construct as a hive structure. The hive structure is able to provide an excellent supporting effect to make a person&#39;s feet comfortable.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an air cushion, and more particularlyto an air cushion with a hive structure that is able to provide anexcellent supporting effect.

2. Description of Related Art

With reference to FIGS. 6 and 7, a conventional air cushion is mountedon a bottom of a shoe and comprises a housing (30), an upper cushion(31), a center cushion (32), a spring (33), a lower cushion (34) and twoair valve pipes (35). The center cushion (32) has a bottom surface and aspring recess (321). The spring recess (321) is formed on the bottomsurface of the center cushion (32).

The lower cushion (34) has a top surface and a spring recess (341). Thespring recess (341) is formed on the top surface of the lower cushion(34).

The spring (33) is mounted between the spring recesses (321) of thecenter cushion (32) and the lower cushion (34).

The housing (30) covers the upper cushion (31), the center cushion (32),the spring (33) and the lower cushion (34) and has a side.

The two valve pipes (35) are mounted at side of the housing (30).

When the spring (33) is pressed, force applied from the ground can beeliminated to protect a person's feet. However, the spring (33) alsopresses against the housing (30) so that the spring (33) will stabthrough the housing (30) to inject the person's feet.

Furthermore, the spring (33) does not have an enough supporting effectto support the person's weight. The person is easy to feeluncomfortable, when the person wears a shoe with the conventional aircushion.

To overcome the shortcomings, the present invention provides an aircushion to obviate or mitigate the aforementioned problems.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide an aircushion that has an excellent supporting effect.

The air cushion has a body and a supporting cushion. The supportingcushion is mounted inside of the body and has multiple hexagon-shapedholes. The holes are formed through the supporting cushion and constructas a hive structure. The hive structure is able to provide thesupporting cushion an excellent supporting effect to make a person'sfeet comfortable. The air cushion does not need any spring to absorbforce occurring by a person stepping so that the person's feet will notbe injected.

Other objectives, advantages and novel features of the invention willbecome more apparent from the following detailed description when takenin conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to FIGS. 1, 2, 3 and 4, an air cushion for a shoe inaccordance with the present invention comprises a body (10) and asupporting cushion (20).

The body (10) is hollow and flat and has an air chamber (11), a side, anair-entering device (12) and an air-discharging device (13). The airchamber (11) is defined inside of the body (10).

The air-entering device (12) has a pipe (121) and a check valve (122).The pipe (121) has a distal opening and a proximal opening. The proximalopening of the pipe (121) is mounted at the side of the body (10) andcommunicates with the air chamber (11) in the body (10). The check valve(122) is mounted at the distal end of the pipe (121) to allow air enterthe air chamber (11) of the body (10) from environment.

The air-discharging device (13) has a pipe (131) and a check valve(132). The pipe (131) has a distal opening and a proximal opening. Theproximal opening of the pipe (131) is mounted at the side of the body(10) and communicates with the air chamber (11) of the body (10). Thecheck valve (132) is mounted at the distal end of the pipe (131) toallow air to exhaust out of the air chamber (11) in the body (10).

The supporting cushion (20) is a resilient block and has multiplehexagon-shaped holes (21). The holes (21) are formed through thesupporting cushion (20) and construct as a hive structure.

With reference to FIGS. 4 and 5, the air cushion is mounted a bottom ofa shoe. When a person wears the shoe, the supporting cushion (20) andthe body (10) will be deformed. With the deformation of the supportingcushion (20), the force applied by the user wearing the shoe isabsorbed. The air in the air chamber (11) of the body (10) exhauststhrough the air-discharging device (13). When the force is released, theair-entering device (12) inhales the air into air chamber (11) in thebody (10). The supporting cushion (20) and the body (10) return back tooriginal shapes.

The hive structure is able to provide an excellent supporting effect tomake the person's feet more comfortable. Furthermore, the air cushiondoes not have any spring so that the person's feet will not be injected.

Even though numerous characteristics and advantages of the presentinvention have been set forth in the foregoing description together withdetails of the structure and function of the invention, the disclosureis illustrative only. Changes may be made in detail especially inmatters of shape, size, and arrangement of parts within the principlesof the invention to the full extent indicated by the broad generalmeaning of the terms in which the appended claims are expressed.

1. An air cushion for a shoe comprising a body being hollow and flat andhaving an air chamber defined inside of the body; a side; anair-entering device mounted at the side of the body; and anair-discharging device mounted at the side of the body; a supportingcushion being a resilient block and having multiple hexagon-shaped holesformed through the supporting cushion and constructing as a hivestructure.
 2. The air cushion for a shoe as claimed in claim 1, whereinthe air-entering device has a pipe having a distal opening and aproximal opening mounted at the side of the body and communicating withthe air chamber; and a check valve mounted at the distal end of the pipeto allow air enter the air chamber; the air-discharging device has apipe having a distal opening and a proximal opening mounted at the sideof the body and communicating with the air room of the body; and a checkvalve mounted at the distal end of the pipe to allow air exhaust out ofthe air chamber.
